IMPROVEMENT IN APPARATUS FOR BREAKI Specification forming part. of Letters Pa To all whom fit may concern:

Be it known that 1, NICHOLAS H. Bonecounty and State ot' New York, have'invented a new and Improved Apparatus for Breaking the Stems and :Leaves of Tobacco and other Substances; and l do vhereby declare that the following isa full," clear, and exact description thereof, which will enable those skilledin the art to make and use the saine, reference being had to the accompanying ldrawing, forming part'of this specilication, in which drawing- Figure 1 represents a longitudinal vertical section-of this invention.. Y-Fie. 2 is a plan or top view of the same. Fie. 3 is a detached plan of one of the comb-shaped Scrapers.

Similar letters indicate corresponding, parts. 'This invention consists in the arrangement of two crushingrollers, with sharp-edged eircular projections or ribs, which are scalloped shaped Scrapers, the teeth of -whieh tit between the project-ionsof the crushing-rollers, and which are adjustable by set-screws in such a`manner that by the action of the scalloped circular ribs the stems of tobacco, as well as the leaves or other articles passed through between said rollers, are broken and reduced to clear and in proper working order. Av represents a frame, Vmade of wood or any other suitable material, and provided on its top with two groovedways, Bi, capable of receiving the standards B B',- which form the' bearingsbr'the crushingrollers C C'. The standardsB B may be made adjustable by set-screws a, so that the crushing-races can be set closer together or farther apart to suit the work.

TheA crushing-faces of the rollers are com' posed of a series of circular sharp-edged ribs, b b', which are so situated that they interroller tit into the interveningv grooves of `the other roller, and vice versa. The peripheries of the ribs b b are scalloped, as clearly shown in Fig. 1, s o as to form a series of sharp points, which serve to break up in one direction the stems of tobacco, as well as the leaves or any other dry article, such as coee, passing through between the rollers. At thesanie time ot' the crushing-rollers.

tent No. 68,597, dated September l0, 1967- the edges oftheribs, as the saine-pass each other, act like cireularshears, cutting or breaking such stems, leaves, or other articles in a direction at right angles to that in which they are broken bythe 'points of said ribs, and by these means the stems and leaves'of tobacco, lor

other articles to be broken,are separated into small particles, .the size ot' which depends upon the eoarseness of the ribs and scallops. By passing the articles to be crushed repeatedly through the rollers they may be ground up to any desired neness. y

Under the crushing-rollers are situated the comb-shaped Scrapers l) D', which are provided with teeth c c, fitting between 4the ribs From the edges'of the comb-shaped sera pers project lugs or ears (I it', which rest upon the grooved ways ofthe frame and form thefulcra ot' said scrapers. The tail en ds of the scrapers are exposed to the action ot' set-screws ff',

and by means ot' these set-screws the Ateeth. of the Scrapers can be made to bear against the crnshillg-surtaces with more or less power. By the action ot' Athe Scrapers the crushingsurt'aces are kept clean and in proper working order.

Thisapparatus is intended particularly for granulating tobacco, audit has the great advantage orer other machines now used for this purpose that it breaks the stems as wellas the leaves, and no portion ot' the tobacco islost.

I am aware that crushing-rollers have -becn used for breakin g up articles ot' di t't'erent kinds` 5 but such rollers would not serve my purpose vou account of the sha-pe ot' their crushingfaces. I do not claim, broadly, therefore, the use of crushing-rollers for breaking the stems and leaves of tobacco independent olf the parlaicular shape ot' the erushing-suriaces.

TWhat I claim as new, and desire t6 secure by Letters Patent, is-

'.,lhe scalloped sharp-edged circular ribs b b on the rollers() C', in acombination with the eombshaped Scrapers D 1)', 4substantially as and for the purpose setforth.
